CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation under 35 U.S.C. §120 of U.S. patent application Ser. No. 13/458,126 filed on Apr. 27, 2012. The disclosure of the U.S. patent application is hereby incorporated by reference in its entirety.

BACKGROUND

Web applications provide a wide variety of services and data to users over networks. Data is collected, processed, and stored in different locations. Web applications retrieve that data, format it for presentation, and provide it to browsing applications on client devices for rendering websites. Some websites may be static, where the data is non-interactive. Others may provide some interactivity such as additional information through links or activation of web-based modules. In general, however, websites present data in a format and amount that is system generated according to organizational requirements or custom build based on user input and formatting.

Website content comes in variety of forms. Content may include text, audio, video, images, drawings, charts, etc. Validity and reliability of content in many websites may be suspect. In addition, there is a valid danger of malicious code embedded within content. Modern solutions meet demand for website content interaction by attempting to provide safe parsed content to end users. Parsed content solutions include client and server systems. Many need significant updates to preserve synchronicity with, technologies utilized in website construction. However, most parsing solutions fail upon facing frequent website updates. Dynamic nature of some websites make it a near impossibility to have a safe parser solution with high success rate for parsing content from websites. Additionally, customization to suit the variability of websites may also lead to problems in maintaining and hosting database solutions to parse content from websites.

Moreover, those skilled in the art will appreciate that embodiments may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and comparable computing devices. Embodiments may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.

Embodiments may be implemented as a computer-implemented process (method), a computing system, or as an article of manufacture, such as a computer program product or computer readable media. The computer program product may be a computer storage medium readable by a computer system and encoding a computer program that comprises instructions for causing a computer or computing system to perform example process(es). The computer-readable storage medium is a non-transitory computer-readable memory device. The computer-readable storage medium can for example be implemented via one or more of a volatile computer memory, a non-volatile memory, a hard drive, a flash, drive, a floppy disk, or a compact disk, and comparable media.

According to embodiments, a sandbox may be a protected environment shielding external applications and devices from processed content within. A script may be a set of instructions to accomplish multiple-actions upon executions. A cloud source may be any network connected application/device providing a service as a unified entity.

Throughout this specification, the term “platform” may be a combination of software and hardware components for retrieving content from a website through a sandbox. Examples of platforms include, but are not limited to, a hosted service executed over a plurality of servers, an application executed on a single computing device, and comparable systems. The term “server” generally refers to a computing device executing one or more software programs typically in a networked environment. However, a server may also be implemented as a virtual server (software programs) executed on one or more computing devices viewed as a server on the network. More detail on these technologies and example operations is provided below.

Referring to FIG. 1, diagram 100 illustrates an example network diagram, where an application may retrieve content from a website through a sandbox according to some embodiments. The components and environments shown in diagram 100 are for illustration purposes. Embodiments may be implemented in various local, networked, cloud-based and similar computing environments employing a variety of computing devices and systems, hardware and software.

In an example environment illustrated in diagram 100, one or more servers 102 and 104 may provide websites for consumption. Websites may host formatted text, and media such as audio, video, images, charts, drawings, tables, etc. The websites may be formatted in a standard format such a hypertext markup language (HTML). A sandbox environment 106 within a client application may process websites from, web server 1 (102) and web server 2 (104) to provide content associated with the websites to the client application on client devices 110 upon request through networks 108. The network(s) 108 may be any network architecture providing access to the sandbox environment 106 through wired or wireless technology.

Client devices 110 may include a variety of hardware such as desktop computer 112, laptop computer 114, a tablet device 116 such as a slate, and a smart phone 118. The client devices 110 may request content from websites through the sandbox environment 106. The content may include components of the website such as images, text components, media, or combinations. By employing the sandbox environment 106, client devices 110 may be protected against malware that may be embedded in a webpage. Through a predefined communication protocol, the client devices lit) may be enabled to communicate with the sandbox environment 106 enabling them to inject a cloud-based script within the sandbox environment 106 in response to a trigger event and retrieve results of the executed script outside the sandbox environment. By hosting the script in the cloud, extraction logic may be updated outside of the clients.

FIG. 2 illustrates a component diagram of an application retrieving content from a website through a sandbox according to embodiments. Diagram 200 displays an example application hosting a sandbox 204 environment to process websites.

According to some embodiments, a client application 202 may transmit a request 216 an application hosting a sandbox 204 for content from a website. The request may include instructions about the website and how to retrieve the content. The application may retrieve the webpage content 210 and render it using a rendering engine (e.g., HTML rendering engine 206) within the sandbox 204. The application may also retrieve a script 214 from a cloud source 212 to extract the content. The application may inject the script 214 into the website content and execute the script method in response to a trigger event defined by the request 216 from the client application 202. The application may load the results of the execution of the script 214 onto a results array 208 provide to fee requesting client application 202. The results in the array may also be stored for future access.

According to other embodiments, the host application may isolate the loaded webpage within the sandbox. The processes related to rendering may be contained within the sandbox. Thus, the host application may isolate execution of the script and extraction of the content within the sandbox. In some implementations, the cloud-based script 214 may be used to extract content from a website and provide as part of a news feed or similar feed item. For example, a dominant image, title, content, an icon, or similar items may be extracted from a news website and provided as a teaser with a news feed or a search result associated with the website. The extracted items may be selected based on HTML properties, heuristics, or comparable methods. For example, image height, width, aspect ratio, vertical/horizontal position, etc. may be used to select an image from the web page. Similarly, icons, titles, or other elements of the webpage may be extracted in the sandbox 204.

According to yet other embodiments, the application may communicate with, the client application through a communication protocol. The communication protocol may be a standardized communication protocol such as hypertext transmission protocol (HTTP), encrypted communication such as secure http (HTTPS), or others.

According to further embodiments, the application may trigger a mechanism to inject the script into the loaded webpage within the sandbox according to a specified event. The client may provide the specified event through the initial request. The specified event may include a user defined event or a system defined event. Additionally, the mechanism to inject the script may include screening the loaded webpage and the content resulting from the injection for malware. In an example scenario, the client application may submit a request for content including only image data from a website. The application may render the webpage in the sandbox. The application may retrieve a script from the cloud source to extract image data from websites. And, the application may inject the script into the loaded webpage to extract the image data. The extracted image data may be loaded to an array for transmission to the client application.

According to other embodiments, the application may trigger a mechanism to transmit the content to the client outside of the sandbox. The application may load the content into the array according to infractions in the script. In an example scenario, the application may prepare the array according to a transmission protocol expected by the client application. Additionally, the application may receive instructions to customize the array according to the specifications of the client. In an example scenario, the application, may sort the array according to a sort architecture of the client application.

FIG. 3 illustrates an example extraction mechanism retrieving content from a website through a sandbox according to embodiments. Diagram 300 displays a mobile device such as a smart phone 302 requesting content from a website. An application hosting a sandbox environment 306 may render and extract content from the requested website.

According to some embodiments, a user of the smart phone 302 may initiate a request 304 for content from, a website by activating a touch control for the request 304. The application may receive the request 304 and retrieve a webpage 308 for rendering within sandbox environment 306. The application may process the webpage according to a script retrieved from a cloud source and load the extracted content 310 to an array. The extracted content may include individual components from the website such as images or other graphics, as well as textual content such as a title. The application may transmit the extracted content to the smart phone 302 and the smart phone may display the extracted content 312.

According to other embodiments, the application may retrieve the script from the cloud source providing an interlace to update the script. The cloud source may enable authorized external entities to update and refresh scripts. The scripts may be refreshed to optimize extraction to suit dynamic nature of websites. The application may also isolate the client from an update to the script. The application may alter behavior to alternately manage execution of script components unspecified by the request. The application may choose not to execute unspecified components of the script.

According to further embodiments, the application may render the webpage with an HTML rendering engine. The application may update components of the rendering engine dynamically to provide additional functionality such as support for other website construction languages and technologies. In addition, the application may execute a component, of the script matching a specified event, subsequent to detecting the specified event on the loaded webpage. An example may include, executing a component of the script calling for extraction of all audio content from the webpage upon detecting audio content within the webpage.
